# oh-my-obsidian

## What it does

oh-my-obsidian stores architectural decisions, session notes and project context as Markdown files in an Obsidian vault. The `/oh-my-obsidian:setup` command starts an interactive wizard that asks about your domain, stack and team, then generates a folder structure via the `vault-architect` agent. After setup, `/oh-my-obsidian:recall` searches for relevant context from past sessions, `session-save` records current work, and `refactor` reorganizes the vault as the project grows.

The plugin works with Codex through natural prompts and explicit skills (`$oh-my-obsidian-recall`, `$oh-my-obsidian-jev`). Optional Jev integration adds paid external search reranking through the TypeSafe API; it stays disabled until you approve it for a specific project and vault. Jev is not needed for local memory. Git sync is configured separately with three modes: `safe`, `manual` and `team-sync`.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install oh-my-obsidian@claude-community
```

## When to use it
- record architectural decisions and session context in Markdown for Claude Code
- retrieve relevant notes and past decisions via Obsidian vault search
- reorganize vault structure as the project evolves
- generate tailored folder structure through interactive setup wizard
- connect paid search reranking through Jev API

## Example prompts
- Run the Obsidian vault setup wizard: `/oh-my-obsidian:setup`
- Find our past vault-layout decisions in the vault
- Save this session to the Obsidian vault

**Oh-my-obsidian gives Claude Code and Codex persistent, Obsidian-backed project memory.**

AI coding agents are capable but lose context between sessions. Oh-my-obsidian stores project decisions and session notes as Markdown in an Obsidian vault, then helps Claude Code and Codex retrieve the relevant context later. Guided setup, vault maintenance, and approval-based Git sync keep that memory usable without hiding where it lives.

## Why Oh-My-Obsidian?

Most AI coding agents start every session with a blank slate. 

| Problem | What Happens | Oh-My-Obsidian Fix |
| :--- | :--- | :--- |
| **Amnesia** | AI forgets why a decision was made last week | `session-save` records architectural decisions into Markdown |
| **Lost Context** | You paste the same context over and over | `recall` automatically searches the vault for relevant past work |
| **Messy Docs** | Documentation rots and becomes disorganized | `refactor` safely reorganizes the vault as the project evolves |
| **Setup Friction** | Hard to bootstrap a good folder structure | Socratic `setup` interviews you to generate a tailored vault |

---

## Quick Start

### Claude Code Quick Start

```bash
# 1. Add our custom marketplace
/plugin marketplace add https://github.com/hongdangmoo49/oh-my-obsidian

# 2. Install the plugin
/plugin install oh-my-obsidian@omob
```

**Install via Official Marketplace** — (Pending Approval) If installed from the official Claude registry:
```bash
/plugin install oh-my-obsidian
```

*(For local development: `claude --plugin-dir /path/to/oh-my-obsidian`)*

**Initialize** — Run the interactive Socratic setup wizard:

```
> /oh-my-obsidian:setup
```

### Codex Quick Start

Codex reads the repository marketplace from:

```text
.agents/plugins/marketplace.json
```

Add the marketplace from GitHub:

```bash
codex plugin marketplace add hongdangmoo49/oh-my-obsidian
```

Then open Codex and install `oh-my-obsidian` from the plugin directory:

```text
/plugins
```

Then ask Codex:

```text
Set up an Obsidian vault for this project.
```

After setup, you can continue with Codex using natural-language prompts or an
explicit skill name such as:

```text
What did we decide last time about the vault layout?
Save this session to the Obsidian vault.
Show me the vault health check.
Add a note to the vault for today's API decisions.
$oh-my-obsidian-recall Find our prior vault-layout decision.
```

<details>
<summary><strong>What happens during setup?</strong></summary>

The plugin will:
1. Check for the Obsidian desktop app on your system.
2. Conduct a Socratic interview to understand your project (domain, tech stack, team size).
3. Generate a tailored folder structure via the `vault-architect` agent.
4. Offer an optional Obsidian Git choice (`safe`, `manual`, or `team-sync`) after separate approvals.
5. For Codex, offer approval-gated official hooks and optional session history restore after validation.
</details>

## Codex Plugin

Codex support is shipped from a separate plugin root:

```text
plugins/oh-my-obsidian/
```
